docs: replace README with a landing page pointing to the documentation site

The WELA documentation now lives on a dedicated docs site
(https://yamato-security.github.io/WELA/). Replace the long single-page README
with a short landing page that points there, and preserve the originals.

- README.md / README-Japanese.md -> OLD-README.md / OLD-README-Japanese.md
  (their language-switcher cross-links updated to point at each other)
- New README.md: logo, badges, a prominent link to the docs site and its main
  sections, downloads, links to the archived READMEs, and the MIT license

# About WELA
**WELA (Windows Event Log Analyzer, ゑ羅)** is a tool for auditing Windows event log settings.
Windows event logs are a vital source of information for Digital Forensics and Incident Response (DFIR), providing visibility into system activity and security events.
**Unfortunately, default configurations often lead to problems such as limited log retention, insufficient audit policies, and blind spots that reduce detection capability**.
WELA helps uncover these weaknesses and offers practical recommendations to improve audit settings and enhance security visibility.
WELA also assesses log configurations **based on real-world Sigma rule coverage**, allowing users to evaluate what can or cannot be detected under current the settings.

# Features
- Auditing Windows event log audit policy settings.
- Checking **based on the major Windows event log audit configuration guidelines**.
- Checking Windows event log audit settings based on **real-world Sigma rule detectability**.
- Auditing of Windows event log file sizes and suggestions for the recommended size.
- Setting recommended Windows event log audit policy and file sizes.
# Prerequisites
* Windows PowerShell 5.1 or PowerShell Core
* Running PowerShell with Administrator privileges
# Downloads
Please download the latest stable version of WELA from the [Releases](https://github.com/Yamato-Security/wela/releases) page.
# Running WELA
1. Unzip the [release zip file](https://github.com/Yamato-Security/wela/releases).
2. Open PowerShell with **Administrator privileges**.
3. `./WELA.ps1 help` to run WELA and see the help usage.
# Command List
- `audit-settings`: Check Windows event log audit policy settings.
- `audit-filesize`: Check Windows event log file size.
- `configure`: Configure recommended Windows event log audit policy and file size.
- `update-rules`: Update WELA's Sigma rules config files.
# Command Usage
## audit-settings
The `audit-settings` command checks the Windows event log audit policy settings and compares them with the recommended settings from [Yamato Security](https://github.com/Yamato-Security/EnableWindowsLogSettings), [Microsoft(Sever/Client)](https://learn.microsoft.com/en-us/windows-server/identity/ad-ds/plan/security-best-practices/audit-policy-recommendations), and [Australian Signals Directorate (ASD)](https://www.cyber.gov.au/resources-business-and-government/maintaining-devices-and-systems/system-hardening-and-administration/system-monitoring/windows-event-logging-and-forwarding).
`RuleCount` indicates the number of [Sigma rules](https://github.com/SigmaHQ/sigma) that can detect events within that category.
### `audit-settings` command examples

### `audit-filesize` command examples
Check the Windows event log file size with Yamato Security's recommendations and save results to CSV:
```
./WELA.ps1 audit-filesize -Baseline YamatoSecurity
```
## configure
